I would say, that I know about this special dialect more than most of the other Forthers. I have not written more than a few lines of Forth myself. But I have read a lot of Forth code.

Yes, that's me. I decompiled it. And it is the most fun reverse engineering project you can imagine. Expect the unexpected. There is a Forth interpreter hidden in the code and some of word names are still in the code. So you can produc

I wonder if Forth is still used today for some applications of if anyone has stumbled over some production Forth code lately. For me, Forth is a language in which you can easily shoot yourself in the foot. One element more or less on the st

To calculate a simple xor (color=x ^ y) to produce a texture for walls was a common hack in the early days of computer graphics. I used it frequently under DOS. It is still useful for these kind of hacks :-)

In principle, such a list exists. It is called Obfuscated C Code Contest https://www.ioccc.org/ Granted, the code is not really readable. But you can see the awesomeness. Boot Windows 3.0 and DOS with a 4kB emulator. C com

Very similar technique (raycasting), but for different type of data. https://github.com/s-macke/VoxelSpace The text in the README describes the technique very well. The JavaScript code is a little bit more complicated

This looks like a normal postfix to infix notation converter. It transforms "abc++" to "a+b+c". You can call it a decompiler for a very simple stack machine. But it neither accounts for branches nor loops.

As far as I know every function call in and out of WebAssembly or asm.js must run through a foreign function interface (FFI)to translate between different binary interfaces. This can be very costly. Mapping and copying of data is necessary.

Thanks for the game. I am playing through the levels and it is a lot of fun. But so far I have not found an effect that cannot be calculated with the classical Maxwell equations in matter.

I have looked at obsfucated JavaScript code as well as webassembly disassembly. I don't see much difference. What might obfuscate is the fact, that it comes without any libraries. You have to program like in C without any library suppo

This repository compiles asm.js into webassembly [1]. Otherwise, you will have a hard time to convert your Javascript code. You have to implement a JIT compiler and GC too. Webassembly was never designed to be a replacement for JavaScript.

I have tried to explain to you why your message might have been down voted. Nothing else. If I interpret your message that way, others will do the same.

Even though I see no reason to vote you down, there are a lot of reasons not to vote you up. The message from WD is very good news for RISC-V. But to make the claim that it overthrows all other architectures from the throne is not only a b

The 20 lines refer to the pure rendering algorithm. Please read the description of the algorithm. The repo contains also the scripts, to generate the GIF animations on the start page and the tools to extract the maps from the Comanche compu

Indeed, Outcast used the same technique. However, not as simple as this algorithm. They included interpolation for the terrain and polygon rendering for the parts, which are not terrain.

The project is originally a fan page about the game Comanche and the Voxel Space engine. The web demo is just one part and contains mainly JavaScript. The tools directory contain the code which was used to generate the gif animations and th

What you look at, is the whole engine and not just the rendering part. This contains, HTML, CSS, loading and initialization of the maps, clear and flip screen code and especially input device logic. The rendering part in the JavaScript is s

You can't look up and down using this technique. However, you can move the horizon line up and down. You don't recognize the difference for small angles.

This was also my first attempt. But I was too lazy to extract all maps that way.

I removed the map in the dropdown menu.

Sorry, this in an error. The Comanche 3 map is not part of the Github archive. Try the outdated website if you want to see how a Comanche 3 map looks: http://simulationcorner.net/index.php?page=comanche

The simplest techniques for 3D rendering without relying on a GPU and WebGL are indeed (2.5D) raycasting engines (such as this Voxel Space engine). A short google search reveals for example: http://www.playfuljs.com/a-first-
